I am trying to visualize some pointcloud data in Open3d in Python, the screen renders the visualizer but as soon as I try to interact with it, it crashes with the above message. 

    import open3d as o3d
    pcd = o3d.geometry.PointCloud()
    pcd.points = o3d.utility.Vector3dVector(test_coords)
    o3d.io.write_point_cloud("oakland.ply",pcd)

    pcd_load = o3d.io.read_point_cloud("oakland.ply")
    o3d.visualization.draw_geometries([pcd_load])

I couldn't really understand any of the reasons of why it's happening or how to fix this online.
